hey does anyone know if marble is safwe for my fish tank????
got sum left ova from a bench top thinking bout breaking it up and puting it in???? safe??

definitely yes! just give it a good wash and put it in.
that is also a good spawning slate later.

kool its really smooth on one side and ruff on the other what side would be best facing up???? p.s and when i say smooth i mean really really smooth is this best facing down???

the smooth surface up. oscar loves to stick their eggs in the
smooth surface. sometime, they paste it in the tank bottom plate
after bulldozing those substrate.

Marble will be fine. The best way to check if some rock is ok to put in your tank is to pour some vinegar on the rock. If the rock fizzes then it is no good
